SPECIFICATION forming part of Letters Patent N0. 407,872, dated July 30,1889.

Application filed August 13, 1888. Serial No. 282,625. (No model.)

T at whom it may concern:

'Be it known that I, GEORGE O. MOORE, a citizen ofthe United States,residing at Easthampton, in the county of Hampshire and State ofMassachusetts, have invented certain new and useful Improvements inNarroware Looms, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to a loom for simultaneously weaving a series ofnarrow fabrics, and is more particularly intended for weaving that classof narrow elastic fabrics known as goring, and used for forming elasticgores in Congress gaiters or boots, or for other purposes.

The object of my invention is to provide a narrow -ware loom in whichthe different movements will. be strong. and positive, and in which thedifferent parts of the loom will be conveniently arranged and adapted toperform their several functions in the most efficient manner, so thatthe loom may be run at high speed with comparatively little power.

In the accompanying drawings, Figure 1 is a broken-out front elevationof the lower part of my improved loom. Fig. 2 is a similar elevation ofthe upper part of the same. Fig. 3 is a central sectional view ofthelower part of the loom. Fig. 4 is a central sectional view of theupper part thereof. Fig. 5 represents the harnesses and their operatingmechanism in elevation. Fig. 6 is a plan view of the harnesses, showingalso their guiding-rolls and central steadying guide. view of one of theadjustable connections of the two-part bars joining the harnesses withtheir operating-levers. Fig. 8 is a brokenout plan view, with the framein section, of the lower part of the loom to show the shuttle and layoperating mechanisms. Fig. 9 is a detail bottom view of the roller slideon the lever which operates the shuttle-driving bar. Figs. 10 and 11'are detail views showing the cam for operating the shuttle-driving-barlever and the connections of the said lever with said cam. Fig. 12 is apartial end elevation of the loom, looking from the right, Fig. 1. Fig.13 is a detail sectional view of one of the Fig. 7 is a detail guiderails or bars for the lay in connection with the guide-rolls on whichsaid rail or bar runs. Fig. 14. is a detail perspective view showing oneof the cam-slots in the lay for causing the shuttle driving pins toengage and disengage the shuttle. Fig. 15 is a detail front view of aportion of the lay, showing one of the shuttles. Fig. 16 is a section online 16 16, Fig.15, and Fig. 17 a section on line 17 17, Fig. 15. Fig.18 shows one of'the shuttle-driving pins and the plates in which it issocketed. Fig. 19 is a cross-section of one of the shuttle-driving pins.on line 19 19, Fig. 18. Fig. 20 is a detail view illuswarp beams. Fig.21 is a detail sectional beam tension-pulleys. Fig. 22 is a detailelevation from the rear of the loom to show the warp-beams for thenon-elastic warps. Fig. 23 is a plan view of one of the tension-leversfor the non-elastic warp-beams. Figs. 24: and 25 are detail viewsshowing one of the beams for the elastic warps and the tension devicetherefor. Figs. 26 and 27 are detail views showing the take-upoperating-lever and its connection with the'lay and the pawl operatingbar.

A denotes the frame-work of theloom, and B the driving-shaft extendinglengthwise of the loom and provided with usual fast and loosedrivingpulleys B B and with cranks I), connected by pitmen b with thelay C. The lay, instead of swinging in the arc of a circle, as is usual,is mounted on bars or rails c, which are secured thereto, and which runback and forth in a right line horizontally on anti-friction guide-rollsa, turning on bolts or studs fixed to the frame-work of the machine. Thebars or rails c are preferably provided with flanges embracing the rollsaand forming grooves for the reception of the said rolls, as shown bythe detail view, Fig. 13.

By reciprocating the lay back and forth in a right line I avoid the objectionincidental to swinging lays, (particularly i n weaving elasticfabrics,) which results from carrying the shuttles at varying heightsthrough difierent parts of their traverse, the shuttles being tootrating the tension device for the non-elastic.

view to show the construction of the warpnear the sets of warps formingthe tops of the sheds at some parts of the swing of the lay and too nearthe sets of warps forming the bottoms of the sheds at the other parts ofthe swing of the lay. Thus if the lay be carried by arms pivoted at thebottom of the loom the shuttles will be considerably higher in thecenter of the back-and-forth movements of the lay than they will be atthe ends of such movements, and the said shuttles will, when at thecenters of the lay movements, be liable site the driving-pulleys agear-wheel b meshing with a larger gear-wheel d on a countershaftD,which carries a camel for operating the shuttles. The cam dispreferably in the form of an irregular plate orflange cast integral withthe hub by which it is secured to said shaft. The gears 12 d are soproportioned that the counter-shaft rotates at half the speed of thedriving-shaft. Pivoted to a support forming part of the machine-frame isa lever E, connected by a pitman E with the shuttle-driving bar 0,reciprocating back and forth in the lay. The pitman E forms a rigid andpositive connection between the lever E and the shuttle-driving bar 0,thus avoiding the use of straps or other loose connections in theshuttle-operating mechanism. The lever E carries a pin 6, on which ismounted a rollerslide 6, working back and forth in a guide slot oropening a in a horizontal plate or bracketv A attached to the frame ofthe machine. To the roller-slide c are attached two bowls oranti-friction rolls 6 which embrace the flange or rim of the cam d, sothat as the latter rotates the lever E will be vibrated back and forthto give the proper reciprocating movements to the shuttle-driving bar(1', said cam being so formed that the lever E will have an intermittentmovement occasioned by a dwell at the end of each stroke. As the end ofthe flange-cam d at which the sharp curves occur passes the bowls e theroller-slide 6 will turn partly on its pin 6 when the dwell of the leverE occurs, so that the said bowls can accommodate themselves to the sharpcurves of the said cam, and any binding of the parts is therebyprevented, while said bowls will always be in proper contact with bothsides of the camflange, thus insuring strong and steady movements. Thestuds or bolts e on which the bowls e are mounted, preferably passthrough slots 6 in the roller-slide 6'', so that the bowls may beadjusted to take up wear.

Instead of the flange-cam and the roller-slide and bowls on the lever Ejust described, a grooved cam or slot in a cam-cylinder and pin orroller stud fixed to the lever E may be employed; but the flange-cam,bowls, and roller-slide are preferred, as they insure smoother andeasier'movements.

The lay O is provided with a series of camslots 0', in which work theshuttle-driving pins or drivers 0 having universal-joint connectionswith the driving-bar C, said drivers beingpreferably provided withelliptical or flattened portions 0 working 4 in said camslots. Theuniversal-joint connections of the shuttle-drivers is secured in thepresent instance by providing said drivers with balls or spherical heads0 at their lower ends fitting in sockets in plates 0 c screwed to thedriving-bar C. The upper plates 0 have slotted projections or standards0 which receive and embrace the lower parts of the driving-pins c andwhich serve as guides to steady said pins as the latter vibrate back andforth, the ball-and-socket connections of the said driving-pins with theshuttle-driving bar permitting said pins to swivel and turn slightly asthe flattened or elliptical parts 0 thereof pass into and out of thecam-slots c of the lay.

, The shuttles F are guided back and forth on the lay in the usualmanner in this class of looms by means of lipped or flanged guides orshuttle-supports f, which enter grooves j in the shuttles, and thelatter are provided in their bottoms near their opposite ends with slotsf for the reception of the driving-pins 0 said slots being open to thefronts of the shuttles.

From the foregoing it will be apparent that as the shuttle-driving baris reciprocated from the lever E the shuttle-driving pins Working in thecam-slots 0 will be moved alternately into and out of contact with theshuttles, the upper ends of the said driving-pins swinging forward, soas to pass freely beneath the woven. fabric or web as they reciprocatewith the driving-bar, one of the drivers or drivingpins swinging up into.engagement with one end of a shuttle just before the driver at theopposite end of the shuttle swings forward clear of the shuttle to passunder the web, and thus each shuttle will always have a posi: tiveconnection with the driving-bar through one or the other of itsdriving-pins.

The shuttles F are each provided with a cop containing a large quantityof yarn, as fully shown and described in my application No. 282,264,filed simultaneously herewith.

The warp beams or spools G for the nonelastie warps are mounted instandards a a at the upper parts of the loom. The warps run from awarp-beam to an overhead pulley g, thence down to a lower weight-blockpulley g, thence up over two other overhead pulleys g, and thence downto the web or fabric. Each of the lower pulleys g is carried by abracket or block g having a hook supporting a weight 9 The standards ahave studs 9 to enter round holes 9 in the inner sides of thetension-pulleys g so that the said pulleys can turn on said studs, saidpulleys having in their outer sides square holes or sockets g to receivethe squared ends of the warp-beam shafts 9 passing through square holesin the Warp-beam. Around each of the tension-pulleys g passes a metallicfriction band or strap g secured at one end to a studor pin a on thestandard a and at its other end to an eyebolt g screwed into a weightedtension-lever g pivoted on a stud a in the said standard. The weightedor long ends of the tension-levers g are above the blocks or brackets 9each of said brackets permitting the long arm of its corresponding leverg to descend until the friction-strap g, attached to the short arm ofthe lever, is drawn tight enough on its tension-pulley to causesufficient friction to counterbalance the weight carried by thecorresponding bracket g Vhen this equilibrium is reached, the bracketand pulley will remain stationary, with a uniform tension on the warps,the latter running from the warp-beam over the warp-pulleys, as abovedescribed, and being drawn forward with the fabric by the positivetake-up, which will be described hereinafter.

The frictional let-off above described obviates the necessity of usinga' positiy'e let-off, which is objectionable in elastic-fabric looms,particularly in looms for weaving goring or wide elastic fabrics, and ithas all the advantages in the smooth running of the warp yarns of theweighted pulleys heretofore generally in use goring-looms without theinconvenience of requiring the operator to be constantly attending tothe letting down of the warps from the warp-beams to lower the weightedpulleys as the latter are drawn up by the warps in the progress ofweaving.

Variation of the tension of the warps may be provided for by usinglighter or heavier weights g or by providing the levers g with severaleyebolt holes Q12 at different distances from their fulcrums, (see Fig.23,) or by both of these means.

The warp-beam shafts g' are secured in bearing-slots in the standards aby sliding catches a, loosely held to said standards by screws passingthrough slots in said catches. By lifting one of these catches, awarp-beam shaft will be free to be inserted in its slot or removedtherefrom in removing or inserting the warp-beams.

"The rubber warp-beams H are mounted on square shafts 72, having roundedends journaled in hearings in the slotted upper ends of standards h,attached'to the machine-frame.

To each of the warp-beam shafts his attached a tension-pulley 7L2,around which passes a metallic friction-band h attached at one end to ahook on the machine --frame and connected at its other end by a hook 714with a lever 7L5, pivoted to a bracket h and provided with a weight 72which may be adjusted toward and from the fulcrum of said lever tosecure any desired tension on the elastic warps. The beams H slip on andoff from the square shafts h, and the tension-pulleys are secured tosaid shafts by set-screws or in any other suitable way. Instead of thisconstruction I may use for the elastic-warp beams independent shafts andpulleys like those above described for holding the non-elastic warps.

Each web or piece of Woven fabric passes between a pressure-roll I and apositivelydriven take-up roll I, to the shaft of which latter isattached a worm-wheel t, gearing with a worm t on a shaft t having aratchet-Wheel 1' Pivoted to a bracket a near one end of the machine is abell-crank lever K, the long arm of which is jointed to a bracket J onthe lay C, the short arm of said lever being forked to embrace a pin is,attached to a sliding bar 1 extending the entire length of the loom andprovided with a series of collars t to which are pivoted pawls tengaging the ratchet-wheels t on the shafts t Thus as the layreciprocates the lever K will be vibrated to impart longitudinalmovement to the bar I to cause the pawls 2' to turn the ratchet-wheels tand thereby intermittingly rotate the take-up rolls through thewormwheels t, worms 1', and shafts The pressure-rolls I are forceddownward against the take-up rolls I by weighted levers 2', bearingagainst the shafts of said rolls in the usual manner.

The warps in passing to the harnesses run below the warp-guide rolls L,j ournaled in adjustable bearing-plates m, secured to brack ets orsupports m, attached to the machineframe by bolts m passing throughhorizontal slots a in said frame, said slots permitting said brackets tobe adjusted horizontally to locate said guide-rolls nearer to or fartherfrom the harnesses, as may be desired.

lVith long-fibered warps it is desirable that the different sets shouldbe more widely separated from each other to make larger sheds than theshort-fibered warps, and to this end it is necessary to make the upperand lower guide-rollers vertically adjustable. The middle guide-rollneed not be vertically adj ustable, as its lower edge should always beon a level with the weaving-line. To provide for the simultaneousadjustmen-t of the upper and lower warp-guide rolls without changing thevertical position of the middle guide-roll, the bearing-plates m areprovided with curved slots m formed in the arc of a circle the center ofwhich is coincident with the center of the middle guide-roll, and thebolts m by which said bearing-plates m are attached to the brackets m,pass through said curved slots.

Thus by simply loosening the nuts of the boltsim the plates m will befree to be turned on the curve of the slots m thereby simultaneouslyraising or lowering the upper and lower guide rolls, and thus spreadingthe warps guided by said rolls more or less to make larger or smallersheds, the vertical adjustment of the middle guide-roll being meanwhileundisturbed.

In order to operate the harnesses entirely from below and more steadilyand positively than heretofore, they are connected at both ends by rigidlinks or bars a with the harness-operatin g levers 01 01. The levers nare operated positively in both directions by the grooved harness-camsn, and, the levers n are positively connected with the lever 01 (seeFig. 5,) so as to be operated thereby. The harness-cams are constructedin the usual manner to give two, three, or four throws to theharness-operating levers. The cam shown in detail, Fig. 5, gives fourthrows to the harness-operating levers at each revolution, as will be.understood; but cams giving two, three, or other number of throws tosaid levers at each revolution'are also employed, as is usual.

The links or bars n, connecting the harnessframes with theharness-operating levers, are preferably made in two parts joinedtogether by right and left-thumb-screws 91 which may be secured in anyposition to which they may be adjusted by set-screws n By turning theered to change the sheds. The harness-cams n are carried by a-shaft N,provided with a beveled gear a", meshing with a beveled pinion d on thecounter-shaft D. The harnesses are steadied and guided at their ends byantifriction-rolls n mounted on small rods supported by brackets aattached-to the machineframe. The harnesses are also preferably steadiedat'their middles by a guide-bracket n", which may also haveanti-friction-rolls n, to insure easy movements of the harness incontact therewith.

From the foregoing it will be apparent that as the harness-cams rotatetheharness-operating levers will impart positive and steady movements tothe harnesses, with both ends of which said levers are directlyconnected, without the intervention of the objectionable flexible strapsor cords heretofore generally in use, and without requiring anyconnections from above, such upper connections being very much in theway in narrow-fabric looms requiring a large number of warp-beamscontaining the numerous warps. In my improved loom, having the harnessmechanism entirely below the harnesses, the yarns coming down from aboveare brought far enough forward so that they can be conveniently reachedby the attendant when necessary.

The general operation of my improved loom will be readily understoodfrom the foregoing. When the power is applied, the driving-shaft B,through the above-described connections with the lay, reciprocates thelatter back and forth, and the cam 01 on the counter-shaft D operatesthe shuttle-driving mechanism, the beveled pinion d on saidcounter-shaft rotatin g the harness-operating shaft N through thebeveled gear 71. the take up being operated from the lay, asabovedescribed.

I do not wish to be understood as confining my invention to all of thespecific mechanisms hereinbefore described, as the details of my machinemay be varied within the province of mechanical skill without departingfrom the spirit of my invention.

Owing to the fact that the shuttle and harness operating mechanisms ofmy loom are positive and direct, I am enabled to run my loom at aboutdouble the speed of other elasticfabric looms heretofore constructed andat a great saving of power, the movements of my improved loom being sodirect and easy that it The warp-beams are of frame, that the weights donot overhang'the lower part of the frame, and as the weights are thuswithin the space occupied by the base of the loom the loom requiresabout a foot (in width) less of floor-space than the old looms, so thatsix of my improved looms can be placed in the space heretofore requiredfor five of the old looms, which is quite a saving of floor-room in themill. In fact, it

may be briefly stated that the object of my invention is to provide aloom which can be run at high speed with comparatively little power andnoise, owing to the direct, positive, and easily-running mechanismsemployed, the working capacity of the loom be= ing still furtherincreased by the large capacity of the shuttle and warp beams for yarn,thereby avoiding frequent stoppages of the loom for new supplies of yarnfor the shuttles and warp-beams.
